HISTORY
In 1960, Hans-Jürgen Berger developed and produced first photographic flashers. Since having sold the first flasher to the German space company MBB in 1973, the company continuously developed conventional high-power flashers into real solar simulators.
In 1997 Detlev Berger took over the company from his father. BERGER Lichttechnik has since developed a wide variety of products for terrestrial and extra-terrestrial solar simulation and testing of solar modules, arrays and cells and increased business at least fivefold.
